密度和施肥量對吉亞6號籽粒產量的影響

1、    密度和施肥量對吉亞6號籽粒產量的影響    張雪王慶峰李慶鵬王世發(fā)摘要  以亞麻新品種吉亞6號為試材，對密度、肥料、微肥采用3因素5水平二次回歸通用旋轉組合方法，研究了亞麻的高產栽培技術，以期為提高亞麻產量、減少化肥使用量提供參考依據。結果表明，吉亞6號的最佳組合為種植密度450萬株/hm2、播種量41.0 kg/hm2、肥料460.20 kg/hm2和微肥2.85 kg/hm2。在此條件下，吉亞6號平均籽粒產量為2 314.5 kg/hm2。關鍵詞  亞麻;吉亞6號;栽培;籽粒產量  s563.2

4、 provide reference basis for increasing flax yield and reducing fertilizer use. the result showed that the best combination was as follows： 4 500 thousand plants/hm2 planting density，41.0 kg/hm2 sowing amount，460.20 kg/hm2 fertilizer and  2.85 kg/hm2 micro-fertilizer. under this condition， the average grain yield of jiya no. 6 reached 2 314.5 kg/hm2.key words  linum usitatissimum l.;jiya no. 6;cultivation;grain yield基金項目  長春市科技計劃項目（18dy025）。作者簡介
